1.前言一般都知道,气体流速对于燃烧具有很大影响。汽汕机气缸内的气体流速或紊流强度随转速增加而增大,其结果加快燃烧速度,使内燃机高速运转成为可能。对于柴油机来说,燃烧室内空气流动对混合气的形成与燃烧过程有 1. Introduction It is generally known that gas flow rates have a significant effect on combustion. The gas flow rate or turbulence intensity inside the cylinder of the steam Shantou engine increases with the increase of the rotating speed. As a result, the combustion speed is accelerated and the high speed operation of the internal combustion engine is made possible. For diesel engines, the combustion chamber air flow on the formation of the mixture and combustion process
